Frontegg

Customer identity and access management platform built for B2B SaaS. Covers authentication, authorization, entitlements, and multi-tenancy so product teams can ship enterprise features without building and maintaining custom CIAM.

Designed with multi-tenancy from the ground up: manage single or multi-tenant organizations, per-account policies, and white-label branding. Differentiates from generic auth providers by combining RBAC with subscription, feature-flag, and object-level (ABAC) entitlements in a single API. Includes an Admin Portal so customers manage users, roles, and permissions themselves.

Key features:

• Multi-tenancy with per-tenant hierarchies, policies, and branding
• Hosted and embedded login with SDKs for React, Angular, Vue, Next.js, and plain JavaScript
• Backend SDKs for Node.js and Python with auth guards and M2M support
• Entitlements beyond RBAC: subscription, feature flags, and ABAC
• SSO and SCIM for enterprise customers
• Admin Portal for customer self-service and user management

B2B SaaS teams adopt Frontegg to offload login, SSO, and entitlements without blocking enterprise deals. Backend developers protect APIs with middleware and integrate via webhooks and APIs. Terraform provider supports infrastructure-as-code for provisioning.
